We now have 90UL Avgas which is cleared for use on most engines like Lycomings in the UK. It is 20% cheaper than 100LL and our fuel costs are way higher than in the US. I have been running it in by PA28 140 for about a year with no ill effects.

There are many stories just like this one. What is that old saying, "pay me now, or pay me later"? Well, flying is expensive. It took me a long time to come to the conclusion that if I wanted to fly, I was going to have to pay at one end or the other. So, I choose to have the convenience of filling up at the airport with 100LL and take that problem out of the equation. It will be a great day when 100NL (no lead) is available and the lead problem with valves and plugs, is also removed from the equation. See N64KR at http://KRBuilder.org - Then click on the pics? See you Oct. 4 and 5, 2013 - KR Gathering in Mt. Vernon, Il ? MVN Daniel R. Heath -?Lexington, SC -Original Message- I replaced the fiberglass wing tanks in my KR-2 with welded aluminum tanks. Ethanol in the mogas, that I was trying to use, was dissolving the Vinyl Ester resin rather quickly. Rubber components in the carb were being hardened and would not seal. (Lots of fun and excitement when the carb overflows while the engine is running.) Now using 100LL exclusively. The fuel system is good to go now. The tank change out and carb rebuild cost about $1500 and six months down time.

Pure gasoline should be good with glass & plastic tanks... Ethanol degrades certain rubber-ish compounds & the interior of some varieties of fuel-lines... The 'mush-ifying' of fuel-tanks has been a problem for fiberglass boats, too... So even without glass tanks... 'Keep the booze in your glass & out of your gas'...

I didn't see the Cheetah. ?I bought the engine off it and overhauled it for my Super Cub project. ?The carb inlet was completely packed full of fiberglass residue, which was why it fell out of the sky and ended on it's back in a field. ?There was something glass in the fuel system that ended up packed in the carb inlet. The Cherokee 235 had the tip tanks softened to the point where they were deforming from the air pressures in flight. ? -Jeff Scott > - Original Message - > From: Dj Merrill > Sent: 08/03/13 09:45 PM > To: KRnet > Subject: Re: KR> ethanol-free fuel link > > On Aug 3, 2013, at 11:37 PM, "Jeff Scott" wrote: > > > > > I have seen disastrous results from using alcohol contaminated fuel in > > glass tanks.

This last winter the cost of 100LL finally hit my pain threshhold when I realized I had burned $7000 in 100LL during 2012. ?With a $2 per gallon difference, burning Mogas will make a significant impact over the course of a year. ?In February I dragged my old 100 gallon tank out of storage, serviced the electric pump, replaced the filters and hoses, then put it back to use hauling mogas. ?The only alcohol free Mogas in our area is 90 octane AKI and is 35 miles away. ? I have been running a mixture of 80% 90 AKI Mogas and 20% 100LL in both planes. ?The O-200 in the KR and the O-320 in the SuperCub are both 8.5:1 compression engines. ?My KR has sloshed Saf-T-Poxy tanks and the Super Cub has glass tanks that were made with an unknown resin before I bought the project. ?Neither seem to be any worse for having used Alcohol free Mogas.

NetHeads, For those who'd rather burn ethanol-free fuel, there's a website that lists most known vendors in the US and Canada at http://www.pure-gas.org/ . They also have free iPhone and Android apps that will guide you to a nearby station, along with pertinent info such as octane ratings. It is regularly updated by folks like you and me through the web page. I think this has been posted before, so this may be just a reminder. I bought some today for the lawnmowers and the generator, and two more stations popped up near the airport and near where I work. Be advised that auto fuel is more prone to vapor lock, especially under hot conditions, but ethanol-laced auto fuel is even worse. Ethanol (and even auto fuel, depending on what's in it) is famous for dissolving composite fuel tanks and various "rubber" parts in fuel systems, but I've run a lot of it through my vinylester tank and Ellison carb with no detrimental effects. Car fuel burns cleaner in my Corvair powered plane than 100LL, which deposits lead in the combustion chambers and on the valves. I prefer it over 100LL, but only use 93 octane due to the compression of my engine. I have a small piece of N891JF's vinylester tank soaking in ethanol-free auto fuel now, but will continue to run 100LL in it until I'm convinced it won't be an issue. I'm still nowhere near flying, but am hoping to fly it to the Gathering... Mark Langford ML at N56ML.com website at http://www.N56ML.com
